About Universal Chiplet Interconnect Express
草榴社区 Verification IP (VIP) for Universal Chiplet Interconnect Express (UCIe) provides verification of design implementations based on latest UCIe specifications which can be used from IP to system level to accelerate verification closure. 草榴社区 VIP for UCIe enables verification for all topologies and at all signaling interfaces of a UCIe design: Flit aware Die-to-Die interface (FDI) between Protocol layer and Die to Die adapter, Raw Die-to-Die Interface (RDI) between Die-to-Die adapter and Physical layer, and Physical link interface between two dies - for single and multi-module chiplet setups. 草榴社区 VIP Test Suites, pre-built specification tied testcases, and SoC integration setups with IPs help accelerate your time to market with high quality deliverables.
